    Notes: Drug regulation and pricing have put strong pressure on the cost-benefit ratio of the innovative pharmaceutical industry. Therefore a study has been conducted in fourteen large and medium sized companies to determine some important organisational and managerial factors influencing success in pharmaceutical innovation. The study consists of structured interviews with Research Directors and questionnaires, submitted to the heads of the different research departments. The following conclusions are tentatively drawn. Firstly, the data suggest that a threshold investment of approximately $150–200 million is needed to maintain the innovative potential. Above approximately $750 million, ‘economies of scale’ seem to appear in pharmaceutical innovation. Secondly, an incremental strategy aimed at reducing the duration of the development process seems to be more successful than a radical strategy which lays more emphasis on discovery. Thirdly, pure play pharmaceuticals seem to be more successful than the pharmaceutical divisions of conglomerates. Management control, especially the way in which reorganisations are performed, is assessed more positively in pure play pharmaceuticals. Fourthly, the greater emphasis on human resources management in Anglo-American companies, in comparison to continental European companies, seems to be an important explanatory factor for their greater success on the pharmaceutical market.

    Notes: The paper contains a report of a test of Cooper's NewProd model for predicting success and failure of product development projects. Based on Canadian data, the model has been shown to make predictions which are 84% correct. Having reservations on the reliability and validity of the model on theoretical grounds, we set out to test it using data collected in the Netherlands.Following Cooper's methodology, we selected 19 projects, which had already been marketed and of which 9 were clearcut successes and 10 clearcut failures. We also studied 9 additional projects, which had not yet been commercialised, as the basis for a future a priori test. The projects were given a product score according to Cooper's criteria, and predictions compared with the actual experience. Eightyfour percent were correctly classified, as in Cooper's work. From a practical point of view however the variance was too large to allow the predictions from NewProd to be used with confidence to predict outcomes unless they are clearcut.We believe that the drawback of the methodology is that the product score is a simple combination of the various factors involved. No allowance is made for the possibility that one factor alone might be responsible for failure. We have therefore introduced the concept of a threshold value for each factor. A project for which any factor falls below this value will be deemed a failure. Based on a very limited sample of 19 cases an improvement of reliability was made to 95% of 18 out of 19 products correctly classified. The NewProd concept so modified is being applied to the sample of 9 as yet uncompleted projects, and its predictions will eventually be compared with actual outcomes.

    Notes: In the yeast Saccharomyces cerevisiae, PKA and Sch9 exert similar physiological roles in response to nutrient availability. However, their functional redundancy complicates to distinguish properly the target genes for both kinases. In this article, we analysed different phenotypic read-outs. The data unequivocally showed that both kinases act through separate signalling cascades. In addition, genome-wide expression analysis under conditions and with strains in which either PKA and/or Sch9 signalling was specifically affected, demonstrated that both kinases synergistically or oppositely regulate given gene targets. Unlike PKA, which negatively regulates stress-responsive element (STRE)- and post-diauxic shift (PDS)-driven gene expression, Sch9 appears to exert additional positive control on the Rim15-effector Gis1 to regulate PDS-driven gene expression. The data presented are consistent with a cyclic AMP (cAMP)-gating phenomenon recognized in higher eukaryotes consisting of a main gatekeeper, the protein kinase PKA, switching on or off the activities and signals transmitted through primary pathways such as, in case of yeast, the Sch9-controlled signalling route. This mechanism allows fine-tuning various nutritional responses in yeast cells, allowing them to adapt metabolism and growth appropriately.

    Notes: Purpose - The paper addresses the effect friendly and friendship relationships among members of innovation teams on the performance of the teams. Design/methodology/approach - The members of innovation teams may develop friendly and friendship relationships over time. In our study, we focus on the effect of the frequency of such non-work relationships on team performance. For this research, we collected full network data on non-work relationships in a sample of 44 innovation teams and investigate how these "friendly and friendship networks" affect the performance of innovation teams. Findings - As result turns out that the frequency of friendly ties has positive as well as negative consequences on team performance, whereas the frequency of friendship ties positively relates to the performance. Research limitations/implications - The results indicate the importance of informal relations for the performance of innovation teams. Further, it is shown that friendly and friendship relations have different theoretical and practical implications. Future research can overcome the limitations of the presented research by concentrating on larger sample sizes and longitudinal research designs. Practical implications - Building on the results of the study managers can better orchestra innovation teams focussing not only on formal but also on informal contacts. The main practical implication is to strive for friendship contacts and to avoid too strong friendly contacts. Originality/value - The study adds knowledge to the research on informal relationships and performance two-fold. First, the findings testify that friendly and friendship contacts are different and not part of the same dimension, and there is strong evidence for the importance of informal contacts.
